Regarding backup of other OSes to ZFS servers and leveraging ZFS
from there on, I can suggest rsync (or cwrsync in case of Windows
clients). This is easily automatable on clients (push to rsync
server) or on the server (pull from clients), provided that you
set up the security/logins appropriately.

The ZFS-enabled server can take care of snapshotting successful
rsync run results, deduplication if appropriately spec'ed, etc.

I posted an enhanced SMF script and config file snippets on OI
wiki to run the rsync server and take ZFS auto-snapshots after
successful completion of incoming rsync sessions (push mode);
it is even more trivial in pull mode initiated by the server -
it can "mkdir .../.zfs/snapshot/$SNAPNAME" given the proper
access via "zfs allow").
